I'm beginning my tuning journey in MAF only with STFT disabled. Idle and low speed are dialed in but as I attempt to push deeper into the MAF ranges I get some pretty aggressive lean out as the STFT is slow to compensate (I've seen timing pulled over 3 degrees and it make me very sad). I understand that this is expected but not sure to what degree. How much RPM and throttle transient should I filter out for reliable MAF tuning data? <2% throttle delta? <5% RPM delta? In addition to the vehicle specifics below note that the Eforce kit appears to have significantly influenced the MAF in spite of using the original unit. Evidently the giant air cleaner and revised intake plenum require a noticeable MAF to Hz adjustment
